Group for mixing water for bathroom or kitchen

Abstract

A flush-mounted group for mixing water for a bathroom or kitchen, comprising: a body comprising a valve, designed to be installed in a seat having a given depth with respect a finished surface, a fastening means for fixing the body to the seat, which is adjustable on the body to set the depth at which the body is inset inside the seat, a plate mountable on the finished surface to enclose the body inside the seat and which is provided with an opening for accessing the body, a control member for operating the valve, which is connected to the valve through the opening of the plate. The mixing group comprises a coupling means for connecting together the valve and the control member, which can be adjusted so as to vary a distance between the control member and the valve and ensure correct positioning of the control member inside the opening.

The invention claimed is: 
     
       1. A flush-mounted group for mixing water for a bathroom or kitchen, the flush-mounted comprising:
 a body comprising a valve, configured to be installed in a seat having a given depth with respect to a finished surface; 
 a fastening member for fixing the body to the seat, adjustable on the body to set the depth to which the body is inset inside the seat; 
 a plate mountable on the finished surface so as to enclose the body inside the seat and comprising an opening for accessing the body; 
 a control member for operating the valve, connected to the valve through the opening of the plate; and 
 coupling means for connecting together the valve and the control member, said coupling means being adjustable to vary a distance between the control member and the valve and ensure correct positioning of the control member inside the opening, wherein 
 the valve comprises a female threaded connection in a head of the valve, and 
 the coupling means comprises a threaded rod engaging with the female threaded connection, the distance between the control member and the valve being variable by screwing or unscrewing the threaded rod into/from the female threaded connection in the head of the valve. 
 
     
     
       2. The flush-mounted group according to  claim 1 , wherein said control member comprises a surface configured to face a user during use, the surface being substantially coplanar with the plate when the control member is correctly positioned inside the opening. 
     
     
       3. The flush-mounted group according to  claim 1 , wherein said coupling means comprises a toothed wheel at one end of the threaded rod and said control member comprises a cylindrical portion having a profile for coupling together with the toothed wheel. 
     
     
       4. The flush-mounted group according to  claim 3 , wherein the coupling profile is on an inner side surface of the cylindrical portion and an outer side surface of the cylindrical portion has a diameter corresponding to a diameter of the opening. 
     
     
       5. The flush-mounted group according to  claim 3 , wherein the valve comprises a surface portion including teeth which can be engaged with the coupling profile of the cylindrical portion. 
     
     
       6. The flush-mounted group according to  claim 1 , wherein the body comprises
 a second valve, 
 a second control member for operating the second valve, connected to the second valve through a second opening in the plate, and 
 a second coupling means for connecting together the second valve and the second control member, said second coupling means being adjustable to vary a distance between the second control member and the second valve and ensure correct positioning of the second control member inside the second opening. 
 
     
     
       7. An assembly method for a flush-mounted group for mixing water for a bathroom or kitchen, the assembly method comprising:
 mounting a body comprising a valve inside a seat having a given depth with respect to a finished surface; 
 adjusting a fastening member for fixing the body to the seat to set the depth to which the body is inset inside the seat; 
 mounting a plate on the finished surface to enclose the body inside the seat, the plate comprising an opening for accessing the body; 
 coupling a control member together with the valve through the opening in the plate; and 
 adjusting a coupling means connecting together the valve and the control member to vary an amount by which the control member projects from the valve and ensure correct positioning of the control member inside the opening, wherein 
 the projection between the control member and the valve is varied by screwing or unscrewing a threaded rod of said coupling means into/from a female threaded connection in a head of said valve. 
 
     
     
       8. The assembly method according to  claim 7 , wherein
 said coupling means comprises a toothed wheel at one end of the threaded rod and said control member comprises a cylindrical portion having a profile for coupling together with the toothed wheel, and 
 said coupling the control member together with the valve comprises mounting the cylindrical portion of the control member onto the toothed wheel of the coupling means. 
 
     
     
       9. The assembly method according to  claim 8 , wherein:
 the coupling profile is on an inner side surface of the cylindrical portion, and 
 an outer side surface of the cylindrical portion has a diameter corresponding to a diameter of the opening and a surface portion of the valve comprises teeth configured to be engaged with the coupling profile of the cylindrical portion, and 
 said coupling the control member together with the valve further comprises mounting the cylindrical portion of the control member onto the surface portion of the valve. 
 
     
     
       10. The assembly method according to  claim 9 , wherein said coupling is performed by axial sliding of the control member on the toothed wheel and on the surface portion, along an axis of the valve. 
     
     
       11. The assembly method according to  claim 10 , wherein adjusting the coupling means for connecting together the valve and the control member comprises screwing or unscrewing the threaded rod along the axis of the valve.
